stering, by photography or otherwise, the states and variations of any of the terrestrial magnetic elements.

An instrument for measuring the intensity of magnetic forces; also, less frequently, an instrument for determining any of the terrestrial magnetic elements, as the dip and declination.

Pertaining to, or employed in, the measurement of magnetic forces; obtained by means of a magnetometer; as, magnetometric instruments; magnetometric measurements.

Pertaining to, or designating, a force producing magnetic flux, analogous to electromotive force, and equal to the magnetic flux multiplied by the magnetic reluctance.

at quantity of electricity of low tension, and hence adapted to the exhibition of electro-magnetic phenomena. [R.]

The treatment of disease by the application of magnets to the surface of the body.

Relating to biomagnetism.

Animal magnetism.

To deprive of magnetic properties. See Magnetize. If the bar be rapidly magnetized and demagnetized. A. Cyc.

A body having diamagnetic polarity.

Pertaining to, or exhibiting the phenomena of, diamagnetism; taking, or being of a nature to take, a position at right angles to the lines of magnetic force. See Paramagnetic. Diamagnetic attraction. See under Attraction.

In the manner of, or according to, diamagnetism.

The science which treats of diamagnetic phenomena, and of the properties of diamagnetic bodies.

A mass, usually of soft iron, but sometimes of some other magnetic metal, as nickel or cobalt, rendered temporarily magnetic by being placed within a coil of wire through which a current of electricity is passing. The metal is generally in the form of a bar, either straight, or bent into the shape of a horseshoe.…

Of, Pertaining to, or produced by, magnetism which is developed by the passage of an electric current. Electro-magnetic engine, an engine in which the motive force is electro-magnetism. -- Electro-magnetic theory of light (Physics), a theory of light which makes it consist in the rapid alternation of transient electri…

The magnetism developed by a current of electricity; the science which treats of the development of magnetism by means of voltaic electricity, and of the properties or actions of the currents evolved.
